UK deliveries. Contact our well informed sales team. 655M13 is an alloy case hardening steel. Characteristics of the 655M13 steel specification are toughness arising from the use of nickel and a more uniform hardness produced by the use of chromium. 655M13 is specifically designed for carburising to give a very hard case with a strong core. 655M1. Heat Treatment - Carburising Temperature. Heat to 890?C/920?C and soak for the necessary time to obtain the desired carburised depth. Single Quench Treatment: Heat the carburised 655M13 parts to 800/820?C and quench in oil. Double Quench Treatment: Heat the carburised 655M13 parts to 850/880?C, cool in oil or air then re heat to 760/780C and quench in oil. Tempering: After hardening temper at 150?C for 2 hours minimum, and allow to cool in air to give the 655M13 tool a final surface hardness in the region of Rockwell C60/62. 655M13 held on stock and delivered throughout the U.K.
